Patent FR-2003871-A1 (FR)
Title: Process and plant for distillation in particular of salt - water
IPC: C02F1/04
Filed: 1969-03-12
Abstract: Salt water e.g. sea-water, is carried out inside an evaporation space which makes possible continuous removal of the distillation residues, without formation of scale. The water to be distilled is finely dispersed at a temperature lower than its boiling point under ordinary atmospheric conditions. This is then brought into intimate contact with a heat-source, whose temperature is greater than the boiling point of water, so as to rapidly vapourise at least part of the water. The supper-heated vapour is condensed and further cooled by heat exchange with incoming water to be distilled thereby minimising heat losses. Thus an atmoised spray of water to be distilled and superheated steam are injected simultaneously into the distillation chamber, where instantaneous evaporation occurs, and the salts which crystallise out from the liquid, fall of gravity to the floor of the chamber, instead of depositing as a scale on the walls.

Title: Plastics wrapping for annulus - esp tyre or coiled cable is predeformed to fit round annulus
IPC: B29C67/00
Filed: 1971-10-06
Abstract: A method of making pre-deformed plastics film winding material for winding annular objects, such as motor tyres or coiled cables, consists of winding the film around a specially shaped roller so that it adopts the shape of the roller. Pref. the roller has max. and min. dias. and a transverse shape so that when a melted plastics film is wound around it and continuously cooled, the film adopts the required permanent deformation. Typically, the deforing roll bulges out to a wider dia. at the centre and tapers symmetrically towards the ends, its maximum dia. being always less than that of the tyre or coil to be wrapped. The deformed sheet is subsequently wrapped circumferentially around the annulus and automatically fits to it so that the edges of the sheet can be sealed by welding.

Title: Plate type heat exchanger for high pressure and temp - made up of autonomous compartments with individual inlets and outlets
Inventor: DOSTATNI ALBERT WOJCIECH
IPC: B21D53/04
Filed: 1974-03-11
Abstract: A heat exchanger includes a bundle made up of autonomous compartments laid side by side. The compartments are formed from two rectangular preformed metal sheets welded along their edges to give a seal, these compartments being off-set to one another in the bundle in the longitudinal direction so that they are positioned in a stepwise manner. Along the shortest edges of the rectangular compartment, integral with the compartment and extending the whole length of the edge, are inlet and outlet headers at opposite ends respectively. In the bundle all the inlet are at one end and all the outlet headers are at the other end. Used in high press and temp. heat exchange where there is limited space, e.g. in nuclear power stations of the P.W.R. type. The autonomous compartments give better sealing of the plates than gaskets, and if a fault occurs, the specific compartment can be isolated without dismantling the bundle. It is easier to mfr. and test than an all welded plate bundle.

Title: Closed cycle gas turbine generator installation - uses secondary circuit to extract waste heat from turbine
IPC: F01K23/02
Filed: 1974-04-05
Abstract: The gas is heated by a non-gaseous heat source such as nuclear reactor.
